Not much change from the last map… mostly some expansion of the 4-8″ contour over the mountains and cutting back totals a little bit on the parts of the fringes. I don’t trust how bullish the models are on the snow maps because it looks like temperatures may end up a bit warmer than the […]
With what is hopefully our last snow threat for the season in the greater D.C. area, there is still a fair amount of uncertainty with the ultimate track of the system in addition to how wet it is. Lower than normal confidence with this forecast, which favors the Euro more than the GFS. My forecast […]
UPDATE March 2nd, 2pm EST: After seeing the latest model forecasts and trends, I would probably shift the 4-8″ and 8-12″+ contours south by about 15-20 miles. — Shifting everything a bit south from the initial forecast and added locally 12″+ wording for the mountains. Accumulations are for snow and sleet, though it will be […]
Meteorological spring is here, but winter isn’t done with us yet. Most of the region will actually start off as rain, but a very strong cold air mass will push southward, bringing the low-level air below freezing and changing areas over to freezing rain and sleet before finally transitioning to snow. The models are handling […]
Same general theme, with a slight shift south along the southern edges and a more pronounced southern shift towards the upper part of the map. Risks are generally to the higher side on the southern fringe areas if the models are to be believed (especially if the overnight front-end thump is fairly wet).
The DC-Baltimore-Philly areas are expected to miss out on the more significant accumulations yet again as bothersome low-level temperatures above freezing and March climo. rear their ugly heads. One of the saving graces with this event is the onset of snow will be overnight, though this did not really help the I-95 corridor and points […]
There were some detail changes due to adjustments in the storm track, which mostly affected central/northern PA, southern VA and the Delmarva Peninsula. Higher confidence in the higher snow totals brought some upscale changes to northern VA. It’s still a low confidence forecast overall, with both upside and downside risks across most of the impacted […]
